Arm Intervention/treatment
Experimental: Intravenous Dose Group 1, 2, and 3
Intravenous Dose Group 1 starting at 0.1 mg/kg and escalated in Dose Groups 2 (0.2 mg/kg) and Dose Group 3 (0.1, 0.2, 0.3, 0.4 mg/kg, titrated based on titration rules, administered every 14 days)
Biological: Sotatercept
Sotatercept is dosed intravenously every 14 days. The dose a subject receives will depend on the randomization arm and the dose group.
Other Name: ACE-011

Experimental: Subcutaneous Dose Group 1, 2, and 3
Subcutaneous Dose Group 1 starting at 0.13 mg/kg and escalated in Dose Groups 2 (0.26 mg/kg) and Dose Group 3 (0.4 to 0.5 mg/kg, titrated based on titration rules, administered every14 days)
Biological: Sotatercept
Sotatercept is dosed subcutaneously every 14 days. The dose a subject receives will depend on the randomization arm and the dose group.
Other Name: ACE-011

Primary Outcome Measures :
  1. Pharmacokinetics (Cmax) [ Time Frame: 28 days ]
    Maximum observed concentration in serum

  2. Pharmacokinetics (Tmax) [ Time Frame: 28 days ]
    Time to maximum concentration

  3. Pharmacokinetics (AUC 28d) [ Time Frame: 28 days ]
    Area under the concentration-time curve

  4. Pharmacokinetics (t1/2,z) [ Time Frame: 211 days ]
    Terminal half life

  5. Adverse Event [ Time Frame: 211 days ]
    treatment emergent adverse sevents (TEAEs) and number of subjects with TEAEs.

Secondary Outcome Measures :
  1. Efficacy [ Time Frame: 113 days ]
    Change in mean hemoglobin concentration between baseline and day 113

  2. Bone Turnover [ Time Frame: 211 days ]
    Change in serum bone biomarker concentrations between baseline and end of study (day 211)
